United have signed goalkeeper Luke Daniels for an undisclosed fee from West Bromwich Albion.
The 27-year-old has penned a two-and-a-half year contract with the Iron.He comes in at an important time, after Sam Slocombe and James Severn both broke arms in Saturday's game against Bristol City.
A former Baggies academy product, he made his league debut for them in August 2013.
He came on as a 77th-minute substitute for the injured Ben Foster to help earn a Barclays Premier League point in a goalless draw at Everton.
In the same campaign Daniels also started both the Baggies' Capital One Cup ties with Newport and Arsenal.
He enjoyed a successful two-month loan spell at Southend United in the first half of the 2011/12 season.
The keeper, who has previously experienced loan spells at Bristol Rovers, Rochdale, Charlton, Tranmere, Shrewsbury and Motherwell, made nine appearances for the Shrimpers, including four FA Cup ties.
He spent a successful season on loan at League Two Shrewsbury in the 2008/09 season, where he gained valuable first-team experience.
The Baggies keeper played a starring role in the Shrews' play-off semi-final second-leg against Bury, making a crucial 31st-minute penalty save before pulling off two stops in a successful penalty shoot-out.
Daniels was in fine form in the Wembley final but could do nothing about Gillingham's last-gasp winner.
The young keeper, who sealed his first professional contract in July 2006, joined the Baggies in 2004 after being released by Manchester United.
He had spent seven years at Old Trafford before being offered a trial at Albion.
His form between the sticks for the reserves saw him make his international debut for England Under-18s in a 2-1 win over Slovenia in April 2006.
